CS 115 Reading: Week 8

Functions

This topic is SUPER important. Take the time to understand it now, because it is not going away.

By the end of Week 8, you should be experimenting with:

• Calling functions that other people have written
• Defining your own simple functions
• Tracing the execution of programs with functions
• Understanding parameters and return values

Suggested readings:

• Start with the "Notes: intro to functions" slides posted on Moodle.
• Proceed to the the CS Circles section on defining functions.
• For a more rigorous perspective, read the How to Think Like a Computer Scientist section on functions (stop at "A Turtle Bar Chart")
• Read Chapter 6 of your textbook, but don't get too bogged down in the examples with graphics.
